Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629870, here are decompositions:

3 + 8629867 = 8629870
23 + 8629847 = 8629870
47 + 8629823 = 8629870
107 + 8629763 = 8629870
131 + 8629739 = 8629870
191 + 8629679 = 8629870
233 + 8629637 = 8629870
257 + 8629613 = 8629870

Showing the first eight; more decompositions exist.
